T o all 'whom it may concern:

, l feet in the feedv trough 2, or getting entirely Be it known that l, BENHARD J. BUTLER, a

into the trough, a series of doors 5, hinged at citizen of the United States, residing at Lake l their'upper ends to the railing 4, normally Mills, in the county of Winnebago and State close the openings between the posts 3. of lowa, have invented certain new and usei While the hogs are feeding, their heads will ful Improvements in Combined Feed 1Heaters l hold the doors in the position indicated by and 'l`roughs; and l do hereby declare the dotted lines in Fig. 3. Assoon as thc hogs following to be a full, clear, and exact de-. move away from the feed trough, the doors 5 scription of the invention, such as will cnwill return to their normal position,under the able others skilled in the art' to which it apaction'of gravity. l ertains to make and use the same. y i The inner wall of the feed trough 2 extends My invention relates to combined feed considerably above the outer edge of the said heaters and troughs, especially adapted for trough, and is indicated by the numeral 6. use in feeding hogs, and has for its object to The said wall 6 forms the outer wall of a priimprove the same in the several particulars mary combustion chamber 7 and a supply hereinafter noted. Y vtank 8. i The said supply tank 8 is located To the above ends, the invention consists above said ccmbustionchamber 7 and is of the novel devices and combinations of de adapted to holdcooked liquid feed. An apvices hereinafter described vand defined in the proxirnatelyy horizontal partition 9 extends claim. across the intermediate portion of the wall 6, In the accompanying drawings,which illusthereby forming the top of the combustion trate the invention, like characters indichambe'r`7 and the bottom of the supply tank cate like parts throughout the several views. 8. The partition 9 is preferably made higher Referring Vto the drawings Figure 1 is a atit-s center and slopes downward toward its view in side elevation, looking at the front of outer edge, in order that the feed within the the improved device, but with some parts resupply tank 8 will run to the outer edge moved and others broken away..` Fig. 2 is a thereof. A smoke stack 10 is supported at view principally in horizontal section, taken the center of the partition 9, with its smoke on the line m2 r2 of Fig. 3, but with some passage extending through said partition. parts shown in full and other parts broken For the purpose offwithdrawing the feed away. Fig. 3 is a from the supply tank 8, a pipe 11 is set in the wall 6 just above the bottom of said supply view in vertical section,

taken on the line als x3 of Fi 2; and Fig. 4 is tank, withits ends projecting slightly beyond To the inner proa detail view` in vertica section, taken through the central portion of the fuel chameither side of the wall 6.

.jecting end of the pipe 11 is secured apiece ber, on the line x4 x4 of Fig. 1.

The improved device is constructed of of hose 12 to the free end of which is secured concrete. a rope or cord 13. As is evident, when it is The numeral 1 indicates a cylindrical base desirable to withdraw a portion of the feed adapted to rest upon the ground. A feed from the supply tank 8 and deliver the same to the feed trough 2, the free end of the hose troughZ, having a concave bottom, is formed 12 is lowered into the feed by means of the cord 13; and then by raising the free end of slightly above the base 1 and concentric with the outer edge thereof. Said feed trough is. also set in from the outer edge ofthe base 1 a the hose above the feed by means of the cord 13, the flow of feediis stopped.

To keep the feed warm in the supply sufficient distance to leave a platform 1ai 8, a fuel chamber 14 is formed upon upon which the igs may stan with their front feet, while 'ceding p To prevent the hogs from crowding one 1 and projects outward from the wall 6, and another,and running their snouts along the is provided with a suitable grate 15 which extends into the primary combustion chamber. The fuel chamber 14 is also provided feed trough 2 while feeding, ar series of laterally spaced posts 3 are set around the with a damper-equipped door 16. Within outer edge of the feed trough 2, with their lower ends embedded in the cement. A rail-` ing 4, bent toconforrn to the curvature of the feed trough 2, is secured lto the upper ends of the posts 3. I

To keep the tank the base the primary combustion chamber 7 is another or secondary combustion chamber 17 formed by a vertical wall 18 extending from the base 1 to the partition 9. An opening 19 hogs from putting their front l is formed in the wall 18 to afford communication between the primary and secondary I combustion chambers. To cause the smoke and products of combustion t0 Wall 20 extends transversely across the primary combustion chamber between the opening 19 and the fuel chamber 14.

e operation of the improved device may be brieliy stated as follows :`First, a lire is built in the l'uel chamber, and the products of combustion and the smoke will pass .annular primary combustion Vchamber through the openingl 19 into the secondary combustion chamber, and. thence stack, thereby thoroughly heating the Walls ol the feed trough and the Walls and the bottom of the supply tank, After the device is thoroughly heated, the feed is placed in the supply tank; and, as is evident, Will be kept Warm long after the fire has been allowed to go out.

The large body ol' concrete contained in the structure will hold a great deal of heat, and Will not, as is evident, cool quickly, as would be the case With a construction of metal. The entire body of the device, it will be noted, is in the form ol' a monolithic concrete structure.

What I claim is A heater of the kind described, constructed of concrete and having a combustion cham ber, a supply tank and a feed trough surrouinliin said combustion chamber formed as monolithic, in combination rack extending above said trough, and rigidly secured to the said monolithic structure.

In testimony whereof I aHiX my signature in presence ol' tWo Witnesses.
